There is something about the concept of eternity that drives us humans absolutely insane. Is not precisely the idea of an infinite existence, is this crazy feeling of wanting to eternally hold to particular experiences that evoke great sensations inside us. Going back to where everything started, the idea of wanting to make a pleasant moment perpetual is a very obvious and expected behavior; who wants to experience the sadness of eating the last scoop of an ice cream right? No one wants to finish a bowl because is so good. We know that at some point we are going to have enough, that incredibly pleasant moment or experience is not going to be crazy appealing forever. Precisely because is not going to last forever, we develop a momentaneous sense of eternity, we really really like what we are experiencing, and we want more of it. We want all the ice cream we can possibly have until a stomach ache tells us the opposite (But we do need that stomach ache to happen to understand that there is nothing else stopping us from getting what we want but ourselves). This is pure human nature, we don’t appreciate being told what to do, we don’t want to be treated like kids; we will learn our way (and most of the times this turns out to be very painful).
